Abstract
A method for producing a marked container (12), includes the following steps: a first step (E1) of heating, beyond a glass transition temperature, at least one shape-changing portion of the thermoplastic material wall (17) of a preform (14); and a second step (E2) of forming the container by injecting a pressurized fluid into the body (16) of the preform (14) such as to change the shape of the heated portion of the wall (17) by stretching it; and a step (E0) for marking the preform (14), during which a mark (39) is provided on the shape-changing portion of the wall (17) such that the mark (39) is stretched at the same time as the wall (17), during step (E2) after forming.
Claims12
Method for obtaining a marked container (12) comprising the following steps:
- a first step (E1) for heating beyond a glass transition temperature at least a portion to be deformed of the wall (17) of thermoplastic material of a preform (14);
- a second step (E2) for forming the container by injection of a fluid under pressure into the body (16) of the preform (14) so as to deform by stretching the heated portion of the wall (17);
- wherein the method further comprises a step (E0) for marking the preform (14) during which a mark (39) is made on the portion of the wall (17) to be deformed so that the mark (39) is stretched at the same time as the wall (17) during the subsequent forming step (E2).
